MOLDING-MACHINE.

To all whom it may concern: V ,Be it known that I, JOHN E. WILCOXEN,

' citizen of the United States, residing at South Bend, in the county of St, Joseph and State of Indiana, have invented certaln new and useful Improvements in Molding Machines, of which the following isa spearfication. 7 j j TlllS lnventlon; relates to improvements 1n molding machlnes and has forits .partlcularobjects to provide means whereby articles can be molded withaccuracy and rapidity. These and other objects hereinafter setforth and claimed, are attained by the means illustrated in the accompanying drawings "in which Figure 1 is a perspective View of my im proved device, the parts being adjusted in position for filling the drag of the flaskf Fig. 2 is a like viewshowing the parts after,

the flask is entirely filled. Fig. 3 is a similar view showing the drag andthe cope .of

. the flask separated from the'pattern. Fig. 4

is a detail View of one'of the sliding sleeves with its bracket.

Like reference numerals in all of theflgures of the drawing designate thesame parts.

This device is especially adapted'for pre paring molds for casting axle skeins and is constructed to support a movable pattern which is adjustable to and from the members of the flask and means for separating. said members from said pattern and for closing said members after the pattern is removed.

As preferably constructed the machine embodies a frame 4, having the standardsj5, and vertical guide the standards 5 at each sidejof the frame. Secured upon brackets 7,}which are fixed to back and forth, said pattern comprising a base 10, rotatably mounted upon suitable trucks 11, havingsecured thereon the "hollow skein forms 12, and bails 13, 'said bails being adapted to retain the drag 14 and its .removable platen 15, in close relation to said pattern. 7

A rock shaft 16 is suitablymounted centrally across the top of the main frame and has secured thereto at each end, the walkingbeams 17, to the ends of which are pivoted links 18 and 19, one set being shorter than the other set, and the lower ends ofthese Specification of Letters Patent.

rods, '6 located between projecting from sleeves 21 and 22 respec ..tively, which are adapted to slide freely= upontheguide-rods 6, the former adapted to operate above the plane oftherails 8 and the latterbelow said rails, The rook-shaft 16 has also securedto it, an operatinglever" 23, which when raised or depressed, slides the sleeves21 and 22 in opposite directions. Sleeves 22 carry and are connected together port the drag of the flask during certain or-liftingflbars 26, andsaidgbars are adapted to engage notches 27 in the, edges of the cope.

27 of the flask,the brackets 25 being braced to each v:fother with the angle iron 28. H

The trucks 11 are formed of journals 29 which. are extended at each side and provided with irollers 30,,asshown in Fig. 2..

In operation, assuming that the partsof theflask'are separated and the pattern in a Patented Jan. 23,1912. Application filed hugust 31, 1911, Serial No. 646,956. I V

are 111011111651 upgn, stud 20 by a platform 24, whichis. adapted to suppositiomth erebetween with-the skein forms pro ecting upwardly, the pattern is rotated and the drag is placed on the bottom side thereof as shown in Fig. 1." The drag and the skein forms are then filled with the core forming. material, thoroughly tamped, the

platen plac'edthereon and secured in position by the bails 13, and the assembled parts then reversed with the skein forms in the position above described. The cope is then placedin posit-ion around. the skein forms,,

said pofsition being determined by suitable dowel pins and the sides, 10f the pattern, filled with the core material and tamped, thus completing the filling of the flask around thei pattern, as shown in Fig. 2. Op.-

erating lever 23 is now manipulatedbring ing the frame 24 in close relation under the drag,. and thelifting bars 26 adjacentl'to the notches in the cope, which-are then inserted in said notches. y reversing the operating leiver after the bails 13 have been turned to 'one side from their engagement with the drag, the drag descends supported by the frame 24:, and the cope a'fscends car ried bythe lifting bars 26, freeing the pattern from the flask in a position to be moved out of alinement, as shown in Fig. 3. The operating handle is then manipulated again, bringing the two parts of the flask together with absolute accuracy, with the skein cores projecting into the cope of the flask, in a position to form a perfect casting. After the parts of the flask are brought together, as last described, they are clamped to each other in the usual manner, the lifting bars 26 are removed from the notches in the cope, and the handle again reversed, thereby lowering the flask and contents in a position to be removed for casting.

WVhile the invention has been described for skein molding, it is obvious that it is applicable to other forms wherein a two part flask is employed or a vertical core is used.

Having thus fully described the invention, what is claimed is:

1. A machine of the character described, comprising a support, a movable pattern truck thereon, a separable flask comprising a cope and drag, and a pivoted means for simultaneously moving said cope and drag in opposite directions.

2. A machine of the character described, comprising supports, a rotatable pattern mounted upon trucks which are adapted to engage said supports, a separable flask comprising a cope and drag, means for securing one part of the flask to the pattern, and a pivoted means for simultaneously moving said cope and drag in opposite directions.

3. A machine of the character described, comprising a frame, supports fixed to said frame, trucks carrying a rotatable pattern and adapted to move on said supports, guiderods, sleeves on said guide rods, means fixed to said sleeves for supporting the parts of a flask comprising a cope and drag, and a pivoted means for simultaneously moving said cope and drag in opposite directions.

4:. A machine of the character described, comprising a frame, supports fixed to said frame, trucks carrying a rotatable pattern,

and adapted to move on said supports, guide rods, sleeves on said guide rods, means fixed to said sleeves for supporting the parts of a flask, means for simultaneously moving said sleeves in opposite directions, said mov-' ing means embodying ashaft, walking-beams secured thereto, and links connecting the ends of said walking-beams with said sleeves.

5. A machine of the character described, comprising a frame, supports fixed to said frame, trucks carrying a rotatable pattern and adapted to move on said supports, guide rods, sleeves on said guide rods above and below said supports, means fixed to said sleeves for supporting the cope and drag of a flask, and a pivoted means for simultaneously moving said cope and drag in opposite directions.

In testimony whereof I aflix my signature in presence of two witnesses.
